State whether the potential energy of the underlined object increases or decreases as a result of the change described. a hot air balloon lands in a field

A) increase

2) decreases

3) increase

Explanation:

THIS IS THE COMPLETE QUESTION BELOW;

2.State whether the potential energy of the underlined object increases or decreases as a result of the change

1)A personclimbs a flight of stairs.

2)A diverdives into a pool

3)A hot air balloonlands in a field.

Kinetic energy can be regarded as a form of energy which an object posses as a result of motion. It can be regarded as energy that is associated associated with motion.

Kinectic Energy can be calculated using below formula.

K.E= 1/2mv^2

Where m= mass of the object

v= velocity of the object

It should be noted that Kinetic energy of a body depends on the velocity of the body squared. Whenever velocity of a body is doubled, then the kinetic energy of the body will quadruples.

1)A person climbs a flight of stairs.

As the person is climbing up, then he's doing that as a result of increase in his velocity and as the velocity increase, the Kinectic energy increases as he climb up the stair.

2)A diver dives into a pool.

As the driver drives into the pool , his Kinectic energy decrease, because his velocity will reduce as he enter the pool

3)A hot air balloonlands in a field.

The Kinectic energy will increase, because as a result of increase in velocity of the balloon

explanation:

an enlarged virtual image is the answer

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
